LUBRICATINGCUP.

To all whom it may concern Be it known that I, EDWARD F. GLAss, a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented new and useful Improvements in Lubricating-Cups, of which the following is a specification.

My present invention relates to lubricating devices and more particularly to a contrivance of this character especially designed for lubricating the operating parts of air cylinders in air pumps or the like mechani cal elements.

The primary object of my invention is to provide a lubricating device which when used in connection with a pump, will operate consistently therewith consequently obviating the waste of oil when the apparatus is not running. 1

Another object of the present invention relies in the production of a device of this character which in itself consists of but a few parts, consequently it may be easily attached to or detached from the cylinder when desired.

A further object is to provide an improved lubricating device wherein the oil is elevated from a suitable reservoir by capillary attraction and fed consistent with the suction stroke of the piston to the pump cylinder.

lVith the above and other objects in view, my invention relates to such details of construction and in the combination and ar-- rangement of the several parts as Wlll be hereinafter fully described and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings, wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a vertical sectional view of my invention showing a quantity of oil disposed therein, and Fig. 2 is a detail view of the wick and wick supporting element carried within the body portion or container cup.

Referring now more particularly to the drawings wherein is shown a preferred embodiment of my invention, the numeral 10 designates the container cup which, as is shown, is formed of metal. Any desirable or adaptable metal can be used in the construction of this cup, but in actual prac tice cast brass has proven very eflicient and Specification of Letters Patent.

therefore'it has been shown as the preferred form.

For a purpose that will be presently explained, the lower portion or bottom element of the container cup is thickened as shown at 11 and has contingent therefrom an eXteriorly screw threaded projection. The projection just referred to, as well as the thickened bottom element is provided with a vertically extending passage way 12 which normally communicates with the in terior bore of the container at the bottom thereof. To obviate this, however, a verti cally disposed conducting pipe and wick supporting element 18 is employed, the latter being provided upon its periphery adj acent its lower end with screw threads such as shown at 14: for engagement with an eX- teriorly screw threaded recess in the bottom of'the container as shown. This conducting pipe extends toa point near the upper eX- tremity of the interior of the container, thus it is apparent thatthe oil contained in the latter can only be fedthrough the passage way by being elevated above the level of the conducting pipe.

I have provided eflicient means which, as set forth above, is adapted to elevate the oil by capillary attraction and feed the same consistent with the suction strokes of the pump. This means comprises an elongated tubular wick 15 disposed exterior-1y of the conducting pipe 13 as shown and having the suction openings 20 formed in the upper extremity thereof. The length of this wick, is substantially the same as the conducting pipe, in order that it depends a considerable distance in the contents of the container. Upon the provision of suction in the conducting pipe 13 the elevated oil is drawn through the suction opening 20 and above the upper terminal edges of the said suction pipe 13 into the interior thereof and from there to the mechanism to be lubricated.

For purpose of holding the wick 15 in place, and assuring its rigidity during the operation of the pump, a coiled spring 16 is employed and disposed thereabout as is disclosed.

Referring now more particularly to the construction of the container, it is recognized that the same is provided upon its interior surface adjacent its upper extremity with screw threads, for reception of a depending annular flange 17 carried upon a cap element 18, the flange mentioned being oi a]; construction of the wick l5,

provided'with screw threads upon its exterior surface as shown. The cap element, is enlarged at its medial portion as shown at 19, so that the interior capacity of the container is increased to a material extent.

After the cap 18 is screwed tightly into place, and the depending projection fitted tightly in the pump cylinder, the device is ready for operation consistent with the trokes. of. the Piston nthe la t After the oil is disposed in the container, th ame is l vated by capillary c n jacent the upper extremity of the conducti g pip an pm th sucti n st kes of t piston in the, pinup, this oil i drawn within thep pe 13 through the openings 2 and about the upper term nal edges of the said conducting pipe 13 and from there is subseq entlyset into the .Qvli d rs.

1. In a lubricating cup, the combination with an oil co tainer ha ing a pa ge for-med therein to. provide communication.

With a suction element, a conducting pipe continuing passage above the normal oil level n a d; con a ner, and a Wick supported by said pipe an s m a y ten ing above said normal oil level for the elevation of oil under he nflu nce or said su tion element.

2. In a lubricating cup, the combination with an oil container having a passage fol-med therein for communication with a suction element, of a conducting pipe continui ng said passage through the body of oil and to a point above the normal level there of, distributing apertures formed at the upper extremity of said pipe, and a wick supported throughout the length of said pipe for the elevation of oil to said apertures under the influence of said suction element.

3. In a lubricating cup, the combination with an oil container, having a passage formed therein for communication with a suction element, a conducting pipe continuing said passage tov a point above the normal oil level, distributing apertures being formed at the upper extremity of said pipe, and a wick enveloping said ipe and adapted to be supported thereby t roughout the entire length thereof, to, elevate oil to said distributing apertures under the influence of said suction element, through said apertures.-

4. In a lubricating cup, the combination with an oil container formed with a thickencd bottom, of a stem projecting from said bottom, a passage formed, in said stem for communication with a suction element, a conducting pipe removably continuing said passage through the body of said. container, suction openings formed,- in the upper extremity of said pipe, and an emzelopirig wick adapted to besupported by said pipe to extend from the bottom of said container to a point above the normal oil level therein in covering said openings, for the elevation of oil to the latter distribution through said pipe under influence of said suction elemen EDWVARD F.
